The reason is that the test may be falsely normal (false negative) in many cases or abnormally elevated in people who have no cancer (false positive) in others. The main use of CA19-9 is therefore to see whether a pancreatic tumor is secreting it; if that is the case, then the levels should fall when the tumor is treated, and they may rise ...
Hypercalcemia, also spelled hypercalcaemia, is a high calcium (Ca 2+) level in the blood serum. [1] [3] The normal range is 2.1–2.6 mmol/L (8.8–10.7 mg/dL, 4.3–5.2 mEq/L), with levels greater than 2.6 mmol/L defined as hypercalcemia. [1] [2] [4] Those with a mild increase that has developed slowly typically have no symptoms. [1]

Serum levels of carcinoembryonic antigen (CEA) and CA19-9 are often elevated, but are not sensitive or specific enough to be used as a general screening tool. However, they may be useful in conjunction with imaging methods in supporting a suspected diagnosis of cholangiocarcinoma.
These are, however, relatively slow processes [7] [8] [3] [9] [10] Thus fast short term regulation of the plasma ionized calcium level primarily involves rapid movements of calcium into or out of the skeleton. Long term regulation is achieved by regulating the amount of calcium absorbed from the gut or lost via the feces. [7] [8] [9] [10]
The standard definition of a reference range for a particular measurement is defined as the interval between which 95% of values of a reference population fall into, in such a way that 2.5% of the time a value will be less than the lower limit of this interval, and 2.5% of the time it will be larger than the upper limit of this interval, whatever the distribution of these values.
CA 242 is a tumor marker for sialylated Lewis carbohydrates associated with adenocarcinomas and e-selectin-mediated metastatic risk. [ 1 ] [ 2 ] [ 3 ] It is commonly tested along with CEA, CA19-9 , and CA242 for detecting pancreatic cancer . [ 4 ]
